Is it possible to give notice of your resignation too soon?

Question: “I am planning to move out of state this summer. When would be the appropriate time to let my current employer know of my plans? I would like to give them enough notice so they can find a replacement, but I’m concerned that if I let them know sooner rather than later, they might replace me. I would like to work as much as I can.” – NancySee comments below, and send your own question to [email protected].
